VMACHIINE FOR TWISTING AND COVERING CORDS, s60.

SPECIFICATION forming part of Letters Patent No. 408,696, dated August 13, 1889.

Application filed January 16,1889. Serial No. 296,500. (No model.) Patented in Germany September 3, 1888, No. 47,228; in France November 30,1888, No. 194,458 in Belgium December 14, 1888, No. 84,292, and in Austria-Hungary March 22, 1889,

To aZZ whom it may concern:

Be it known that I, WILHELM OLORER,'a

- subject of the Grand Duke of Baden, and a resident of Mannheim, in the Grand Duchy v of Baden, Empire of Germany, have inventedcertain Improvements in Machines for Twisting and Covering Oords,'and theLike, (for which I have been granted patents in Germany, No. 47,228, dated September 3, 1888; in

to Belgium, No. 84,292, dated December 14,1888; in France, No. 194,458,-dated November 30, 1888, and in Austria-Hungary, No. 62,525, dated March 22, 1889,) of which the following is a specification.

I 5 My invention relates to machines for twisting and overspinning or covering threads, Cordage, and the like; and the principal object of the invention is to improve the construction of the flier, whereby it may be 26 utilized for overspinning the core or for twisting the core, all as will be hereinafterset forth. f

In the accompanying drawings, illustrative of my invention, Figure 1 is a front View of a machine embodying my invention and combining in one machine four twisting and overspinning machines driven from one'shaft.

Fig. 2 is a side view of said machine; Fig. 3,

a rear view, and Fig. 4. a plan. The four machines embodied in this compound machine may be all alike. Fig. 5 is a sectional elevation of a modification of the machine adapted for overspinning an untwisted core. Fig.8

is a sectional elevation, and Fig. 7 is an end View, of a modification of the machine illustrated in Fig. 5, but on a larger scale? Fig.

8 is a sectional elevation, and Fig. 9 a front end view, of one machine embodying my in vention. These views illustrate, on a larger scale, the constructionof the several machines combined, as seen in Figs. 1, 2, 3, and

- 4. Fig. 10 comprises two views of the flier detached and on a larger scale than Fig. 8.

In order that my invention may be the better understood, I will first refer to and describe the construction illustrated in Figs. 8 and 9,

. where my invention is shown as embodied in a single twisting and overspinning machine,

where the core is made up of two separate strands.

A is the overspinner as a whole, and B is the core-twister as a whole. Gis the flier of the core-twister, which is secured to the end of a tubular shaft I), mounted in a suitable frame I). This flier carries two spools or bobbins h h, on which are wound the respective strands or m, which form the core.

By reference to Fig. 10 the construct-ion of the flier G may be fully understood. It comprises a bar at, provided at its middle with a screw-threaded socket, which receives the end of the hollon shaft 1). At its ends are armsz' '0', between the extremities of which is secured a removable stretcher is, on which the spools Jr are mounted.

On the inner face of the bar 02 are mounted two arched or curved tension-bars and guides.

These bars have in them holes 0 o, the inner one having three holes -by preference, and the outer one seven holes by preference, the central hole in each bar being aligned with the axis of shaft 1).

The manner of threading the strands w 00 through the holes 0 0 in the tension-bars is clearly illustrated in Fig. 8.

In the same frame I), and aligned with the shaft 1), is another hollow shaft a ,which forms a partof the overspinner A. On the end of the shaft a is secured a disk -O,which has arms a projecting from its face, on which are rotatively mounted the spools cl cl (1, &c., bearing the respective strands :0 00 &c., to be spun over the core as. This core, formed by the twisting together of the two strands m, passes longitudinally through the two shafts a and b and on through an eyelet g, mounted .on the face of disk 0 and aligned with the axis of the said shafts. The several covering-strands 00 are led from their respective spools d through guides e and f to the front 9c of eyelet Where they converge and join the core as. The finished cord or thread 00 passes over a take-up or delivery wheel s,aroupd which it is wrapped once or twice, and is led thence down to a drum or spool 25, on which it is wound up as fast as completed. On the shaft a is secured a pulley or sheave q,whereby the overspinning device A is driven through belt q and on the shaft 0 is a similar sheave or pulley (1 whereby the core-twister B is driven through a belt (1 The cord may pass over a support 1" (seen at the right in Fig. 8) arranged just in front of the point where. the covering-strands converge upon the core.

The two threads 0; 00 forming the core 1; are twisted together by the rotation of the shaft 12, and the tightness of the twist will be proportioned to the speed at which said shaft is driven. The speed at which the take-up wheel .9 and spool t are driven relatively to the speed of the overspinner A will govern the tightness of the overspinning, as will be well understood.

The number of strands in the core and of the strands spun over the core maybe varied almost indefinitely, as may also the relative speeds of the independentlydriven parts. The shafts a and b may rotate in the same or in contrary directions. If only one strand is used in the core, then but one spool It will be mounted on the stretcher 7c.

The principal figures 1, 2, 3, and 4 show a compound machine embodying four machines like that just described mounted in asuitable main frame S and driven from a shaft Q in common. This shaft may be provided with a crank Q, and it has on it a pulley P, from which the several overspinning devices A are driven, and a pulley P, from which the several twisters B are driven. A pulley w on shaftQ is belted to a pulley v on a counter-shaft Q and a pulley n on this counter-shaft is belted to a pulley u on the shaft Q Whereon the take-up wheels 3 are mounted. On this shaft Q is secured a pulley s, which is belted to a pulley s on the shaft Q, on which the several drums t are mounted. Thus all the moving elements of the mechanism are driven from the main shaft Q. By using cone-pulleys the speed may be varied in a well-known manner.

In Fig. 4 the overspinning devices at the left side are shown without any spools (Z on the arms a merely to avoid obscuring the drawings.

It may be remarked that the machine described can be easily modified so as to make overspun cords of which the axial thread or core is not twisted. This is illustrated in Figs. 5, 6, and 7. In eifecting this change the flier G is unscrewed from the shaft 1), which is allowed to remain at rest, and the disk 0, with its attachments, is removed from shaft 0, and replaced by the flier, as seen in Figs. 6 and 7. However, the spools It will be first removed from the rod 70, and spools (1, containing the covering-thread, placed on the arms 11 of the flier. The core 41: is led from a drum I? (seen at the left in Fig. 6 through an eyelet 11 set in the end of shaft ,and thence through the bores in shafts b and a, over the support 1" and take-up wheels, to the spool or drum t. On its way it passes through the central holes 0 in the tension-bars land m on the flier G, and at this point it receives the coveringthreads 00 The stretcher k of the flier may be omitted altogether; but if used in operating in the above manner it must have in it an aperture for the passage of the finished cord.

Fig. 5 is a sectional view merely designed to illustrate how several machines similar to that shown in Fig. 6 may be driven from one common shaft, said view correspondin gin this respect to Fig. 2.

Having thus described my invention, I claim- The combination, with the tubular shaft to which it is fixed, of the flier G, consisting of the bar 72, furnished with a socket at its middle to receive said shaft, the arms 1' i on the respective ends of said bar, the removable spool-carrying stretcher 70, mounted in said arms, and the two arched tension bars mounted on the face of the bar a and provided with holes 0 for the passage of the strands, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
